You could always try thenewboston, he's made 200 android development videos that you can watch for free. They're surprisingly good but sometimes lack in-depth reasoning for how or why things work, so you might have to lookup some concepts to further understand.
Links: Android Dev Videos

Yeah they're not fantastic, but they're not the worst and there's a lot of content there. Like I said, I think the videos are OK but lack reasoning and explanation. In that thread they seem to comment in particular about the C++ videos on which I wouldn't be able to comment; I've only watched a few of the Java and a couple of the Android dev videos.

What kinds of things would you like to make? if you want to make 3d style games then i'd suggest looking up Unity3D. Its free and awesome. lots of great tutorials too. if you're after a course on just making android apps, I'd love to be in on that too :)
